Title: Trouble diagnosing apparatus for oxygen sensor
Inventor: TAMURA HIDEYUKI
IPC: G01N27/26
Filed: 1988-02-25
Abstract: PURPOSE:To eliminate misjudgement, by determining abnormality in an oxygen sensor from the continuation of a state in which an output thereof is between a first set value and a second set value when an engine is within a certain operating area. CONSTITUTION:An oxygen sensor 12 is mounted on an exhaust pipe 5 of an engine 1 to detect the concentration of emission. An output of the oxygen sensor 12 is sent to a control unit 15 having functions as an operating area judging means and an abnormality judging means. In the control unit 15 of such a type, when the engine is in a specified operation area after the completion of warming it up, the oxygen sensor 12 is judged to break down by the continuation for a specified time of a state in which an output voltage VO2 of the oxygen sensor 12 is smaller than a first set value VO2NG1 while being larger than a second set value VO2NG2. This can completely eliminate the possibility of a misjudgement of a trouble in the oxygen sensor 12 even when a base mixing ratio of the engine is lean.

Title: Ribbon cartridge
Inventor: BORISU UKUMARU
IPC: B41J33/26
Filed: 1984-03-07
Abstract: 0 The ribbon (17) has an external run between the type element (25) and platen of a daisy-wheel typewriter. This run stretches between terminal members (59) which protrude from side arms (33 and 34) of the cartridge casing (18) and are fixed to the distal ends of arms (39, 41) pivotally mounted in the casing (18) at (52). The arms (39, 41) are biased downwardly by wire springs (67) to expose the typing line. Ribbon lift levers of the typewriter raise the arms simultaneously to position a selected one of three tracks on the ribbon at the level of the typing point. The terminal members (59) slide on guides (62) at the ends of the side arms (33, 34), constraining the external ribbon run to lie always within and translate within a single plane. The edges of the guides (62) are curged so that the tilt of the terminal members (59) varies as they move up and down, in such a way as to maintain the ribbon tension uniform across the width of the ribbon (17). The arms (39, 41) are flexible and have pivotal play to permit these constraints on the terminal members (59).

Abstract: PURPOSE:To perform the interpolation of polar coordinates and the working of a work with high accuracy by setting the value of an error if this error is caused in the direction of a virtual axis at interpolation of the polar coordinates. CONSTITUTION:It is impossible to show an actual work in the polar coordinates (X, theta) if an error P is produced at loading of the work and the rotational center of the work is shifted to a point O1 from an original point O. When the interpolation of the polar coordinates is carried out in consideration of the error P, it is required to obtain a point Qo where a point Q turns to a C axis and crosses an actual rectilinear axis (Xp axis) and then to obtain a rotational angle thetao covering a position Xo on the Xp axis of the point Qo and the point Q through the point Qo. Therefore the moved position of the point Q on the polar coordinates (Xo, thetao) is shown as Xo=(X<2>+C<2>-P<2>)<1/2> and thetao=tan<-1>(C /x)-sin<-1>(P/(X<2>+C<2>)<1/2>). Under such conditions, the error P is previously set via a parameter.
